For those who have been reading a few of my postings, they are aware of the many Hacker motors in my various models. IMHO, because they work, and work well.

Well, in E-bay, a Hyperion ZS3025-10 motor was for sale at $49.00, shipping included. After checking the specs of this motor, and needing a motor of this size for a recently picked up model, the Hyperion motor was ordered and received.

The Hyperion specifications lists the motor winding resistance at 0.019 ohms, a very good value for this size motor. Using a pair of Fluke 87 meters, my tests show this winding resistance at 0.0265 Ohms. That is still lower than the comparable Hacker motor. (H'mmm, maybe Hyperion is checking winding resistance between one winding and the two other windings shorted together. If so, that is very close to the spec'd 0.019 ohms)

Hyperion also indicates that this motor will pull about 44 Amps at 14.7 Volts DC while turning an APC 12X6SP prop. My tests shows that this motor pulls 25 Amps at 14.5 Volts DC. Don't have an RPM reading, got to track down my optical Tachometer.

Putting an APC-E 13X6.5 prop on this motor looks to be a good match, pulling 38 Amps at 14.1 Volts DC off a 5S1P A123 battery pack.

The Hyperion motor has notably more "cogging" when manually turning the shaft than my Hacker A40 motor, but while running, this totally disappears.

This Hyperion motor looks to be very well made, and IMHO, and potentially a good motor to consider for your next models.

I really like the Hyperion motors. I've had about the same results from the ones Ive owned as you have.

Right now Aircraft World has several of last years versions on super discounts. I picked up a new one for my Bubble Dancer for under $20 shipped! Something like 60% off. I also got one for my new Supra that Im building.

If you select their ems shipping its only $2.50 to ship pretty much anything but kits from japan to the US. Usually takes about 1 week to arrive. Their customer service is excellent as well.

I just tried to find the ten turn version of the motor I picked up for $49. Aircraft world only has the 8 turn version which would not work for my 5S A123's. But, holy cow, the 8 turn version is nearly $130!

Denny that is the newest version for that size motor. Here is the link that I bought my motor from them. By the way I got mine in 10 days from Japan plus we had a holiday during that time MLK day. To bad they don't have the motor size you need when they started the sale they did. They have sold a lot of the discontinued motors since I first found out about the sale.

I got this model FREE from a club member who was not to happy with it. The first flight was interesting, with the model taking a wild left bank on take off. It took full aileron trim to get it to fly level. Will have to check that wing for warps. A total of four flights were made, and the model can do just about anything required or desired. Didn't try 3D, that is not my thing.

After getting that squared away, this is a nice model, with enough power up front to flight straight up out of sight. The Hyperion motor was cold after landing, so flying in summer should not be a problem. A six minute flight resulted in the A123 pack discharging about 1500 Mah. So, I'll be limiting flights to about 5 1/2 minutes.

And, this pilot is getting more and more impressed with that Hyperion motor. For the $50 I paid for it, it is a very good value for the buck.

Denny glad to read you liked the motor. I haven't run mine up yet I need to test it with different props soon. Plane it is going on will be done in a couple of weeks. I bought some servos from that ebay seller good price on hitec 65mg servos shipping was a little on the slow side.

As for my model, and its severe left turn on its maiden flight, If this idiot had looked at the ailerons from the end view with the aileron zero'd out, it would have been obvious. The right aileron was warped 1/4 inch down at the wing tip, the left aileron was warped 1/4 inch up at the wing tip.

Took about two minutes to fix it with a monokote iron. Now, just waiting for good weather to try flying it again.
